The reversion apparently deleted the test/Transforms directory.
Will be re-reverting again.

As it's causing some bot failures (and per request from kbarton).
This reverts commit r358543/ab70da07286e618016e78247e4a24fcb84077fda.

To quote the langref "Unlike sqrt in libm, however, llvm.sqrt has
undefined behavior for negative numbers other than -0.0 (which allows
for better optimization, because there is no need to worry about errno
being set). llvm.sqrt(-0.0) is defined to return -0.0 like IEEE sqrt."
This means that it's unsafe to replace sqrt with llvm.sqrt unless the
call is annotated with nnan.
Thanks to Hal Finkel for pointing this out!

We didn't realize that we could transform the libcall into a vectorized
intrinsic.

Summary:
This patch adds majority of supported by Accelerate library functions to the
list of vectorizable functions.
The full list of available vector functions could be found here:

Test Plan: Unit tests are added.

Also, add several entries to vectorizable functions table, and
corresponding tests. The table isn't complete, it'll be populated later.
